DFCA8

2-way, poppet directional valve with integral T-8A control cavity - control 1-2

SERIES 1 / CAPACITY: 60 L/min. / CAVITY: T-13A

This valve is a 2-position, 2-way poppet cartridge that incorporates an integral pilot control cavity. It controls flow

from port 1 to port 2, exhibits extremely low leakage rates and will accept 5000 psi (350 bar) at both ports. Installing

a pilot solenoid cartridge in the T-8A cavity results in a high flow directional valve. Other pilot options include

manual, hydraulic and pneumatic pilot cartridges.

TECHNICAL FEATURES

NOTE: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required

torque value.

The -8 control option allows the pilot control valve to be incorporated directly into the end of the directional cartridge via the T-8A cavity. These pilot control

cartridges are sold separately and include solenoid operation, air pilot operation, and hydraulic pilot operation. See Pilot Control Cartridges.

Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge

machining variations.

PERFORMANCE CURVES

Compound cartridge (pilot and main stage) assembly information is provided for reference only. Cartridges must be ordered separately and assembled at
